Hello Aireen.
From what you are saying, you are being oppressed by an unclean spirit. This that you are experiencing is not from the Lord.
You say you are a catholic. You say that your psychology instructor is a Christian. So it would seem that back of your mind you understand there can be a difference. That is not to say that a Catholic can not be a Christian, but it is not automatic. So I ask you in all seriousness have you personally accepted the Lord Jesus Christ as your own personal Saviour? You need to claim for yourself His gift of forgiveness of your sins and seek His protection and guidance daily.Once you have unconditionally accepted His free gift of salvation, (and perhaps you have already) Then and only then can you claim the authority of His name to rebuke once and for all any unclean spirit that is oppressing you.
Any vision that will come your way from the Lord will be a vision that will be glorifying the Lord and will give or bring you peace even if part of the message contains some tragic things. Overall the Lord's message will bring you peace and glory to the Lord.
You asked how to test spirits? Any spirit that confesses Jesus is Lord is from God any spirit that will not confess Jesus is Lord is not from God. Now understand that confessing that Jesus is Lord is not just a matter of saying it. The confession will be backed up by actions or other evidences of a submission to Jesus' Lordship.
I believe the very fact that a person is being oppressed by an unclean spirit rather than possessed by it indicates that that person might be in danger, but is being protected for a time by a guardian spirit to give them time to get right with the Lord.
I don't have my Bible handy at the moment, but if you need scriptural support for anything I have posted let us know and either I or someone else can supply them.
OK Airleen, I mentioned rebuking the unclean spirit in the name and authority of Jesus. Some Scripture (quoted from the ESV)
Luke 10:1-20. 1After this the Lord appointed seventy-two others and sent them on ahead of him, two by two, into every town and place where he himself was about to go. 2 And he said to them, “The harvest is plentiful, but the laborers are few. Therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest. 3 Go your way; behold, I am sending you out as lambs in the midst of wolves. 4 Carry no moneybag, no knapsack, no sandals, and greet no one on the road. 5 Whatever house you enter, first say, ‘Peace be to this house!’ 6 And if a son of peace is there, your peace will rest upon him. But if not, it will return to you. 7 And remain in the same house, eating and drinking what they provide, for the laborer deserves his wages. Do not go from house to house. 8 Whenever you enter a town and they receive you, eat what is set before you. 9 Heal the sick in it and say to them, ‘The kingdom of God has come near to you.’ 10 But whenever you enter a town and they do not receive you, go into its streets and say, 11 ‘Even the dust of your town that clings to our feet we wipe off against you. Nevertheless know this, that the kingdom of God has come near.’ 12 I tell you, it will be more bearable on that day for Sodom than for that town.
Woe to Unrepentant Cities
13 “Woe to you, Chorazin! Woe to you, Bethsaida! For if the mighty works done in you had been done in Tyre and Sidon, they would have repented long ago, sitting in sackcloth and ashes. 14 But it will be more bearable in the judgment for Tyre and Sidon than for you. 15 And you, Capernaum, will you be exalted to heaven? You shall be brought down to Hades.
16 “The one who hears you hears me, and the one who rejects you rejects me, and the one who rejects me rejects him who sent me.”
The Return of the Seventy-Two
17
The seventy-two returned with joy, saying, “Lord, even the demons are subject to us in your name!” 18 And he said to them, “I saw Satan fall like lightning from heaven. 19 Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you. 20 Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven.”
emphasis added
You should study this using your favorite Bible version and pray to Jesus about it. As a disciples of Jesus, He has given us authority over unclean spirits. But understand that it is not our authority, but His authority that He has given us to use..sort of as His deputies.
I also posted: "Any vision that will come your way from the Lord will be a vision that will be glorifying the Lord and will give or bring you peace even if part of the message contains some tragic things. "
Please study the following:
Acts 9:10-19. Now there was a disciple at Damascus named Ananias. The Lord said to him in a vision, “Ananias.” And he said, “Here I am, Lord.” 11 And the Lord said to him, “Rise and go to the street called Straight, and at the house of Judas look for a man of Tarsus named Saul, for behold, he is praying, 12 and he has seen in a vision a man named Ananias come in and lay his hands on him so that he might regain his sight.” 13 But Ananias answered, “Lord, I have heard from many about this man, how much evil he has done to your saints at Jerusalem. 14 And here he has authority from the chief priests to bind all who call on your name.” 15 But the Lord said to him, “Go, for he is a chosen instrument of mine to carry my name before the Gentiles and kings and the children of Israel. 16 For I will show him how much he must suffer for the sake of my name.” 17 So Ananias departed and entered the house. And laying his hands on him he said, “Brother Saul, the Lord Jesus who appeared to you on the road by which you came has sent me so that you may regain your sight and be filled with the Holy Spirit.” 18 And immediately something like scales fell from his eyes, and he regained his sight. Then he rose and was baptized; 19 and taking food, he was strengthened. from the ESV.
So, the vision that Ananias was given held some fear for him because of Saul's reputation as an enemy. But in the long run, the whole episode was about glorifying Jesus amongst the Gentiles and the Israelites too.
Also, 1 Corinthians 14:33 " For God is not the author of confusion, but of peace, as in all churches of the saints." from the King James version.
So, I believe that no bad visions and troubling dreams will come from the Lord our God. And if they are coming to us, they are the the work of unclean spirits that can not and will not glorify the Lord Jesus Christ.
Are there guardian spirits? I believe there are. The Bible does not dwell much on them because many people can be seduced into worshiping them instead of worshiping God. However,you can study this from Jesus:
Matthew 18:10. “See that you do not despise one of these little ones. For I tell you that in heaven their angels always see the face of my Father who is in heaven. from the ESV. This passage is the introduction to the parable of the lost sheep. The lost sheep are those who rightly belong to the Shepherd, but are not as yet included in the flock... that is to say, they need to be brought back into the safety of the flock. So yes, there are angels set to watch over us, but we must never worship them.
see also Rev 19:10. Then I fell down at his feet to worship him, but he said to me, “You must not do that! I am a fellow servant with you and your brothers who hold to the testimony of Jesus. Worship God.” For the testimony of Jesus is the spirit of prophecy.
John went to worship the angel, but was forbidden to do so. Contrast this with the attitude of the uncleanness of Satan:
Matthew 4:8-11 Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their glory. 9 And he said to him, “All these I will give you, if you will fall down and worship me.” 10 Then Jesus said to him, “Be gone, Satan! For it is written,
“‘You shall worship the Lord your God
and him only shall you serve.’”
11 Then the devil left him, and behold, angels came and were ministering to him.
Please note the last part where Satan leaves Jesus alone and compare that with :1 Peter 5:6-9. 6 Humble yourselves, therefore, under the mighty hand of God so that at the proper time he may exalt you, 7 casting all your anxieties on him, because he cares for you. 8 Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour. 9 Resist him, firm in your faith, knowing that the same kinds of suffering are being experienced by your brotherhood throughout the world.
and lastly, please study James 4:7 Submit yourselves therefore to God.
Resist the devil, and he will flee from you.
These are faithful promises that the servant of the Lord have been given.
